RAZOR AND LOADING DEVICE THEREFOR Filed July 20, 1933 INVENTOR PatentedAug. 14, 1934 UNITED STATES PATENT OFFICE RAZOR AND LOADING DEVICETHEREFOR Application July 20, 1933, Serial No. 681,259

15 Claims.

This invention relates to a combined razor and magazine which areseparable to enable the razor to be used for shaving apart from themagazine.

The invention has for its object to provide a separate razor and aseparate magazine or loading device which however have co-acting partsfor not only positioning the parts for the loading operation but whichparts have an additional function in enlarging the blade channel of therazor to enable a blade to be easily and smoothly fed into the razorfrom the magazine and at the same time insuring that the cutting edge ofthe blade will travel free. This avoids any chance of the bladecontacting anything until it is in shaving position and the cutting edgeis prevented from becoming dull by any contact with a hard surface.

The razor to carry out the objects of the invention co-operates with thepositioning means in being spread for the reception of the blade andalso functions when the magazine is withdrawn by moving the blade fromthe place where it was deposited by the magazine into a firm positionfor shaving.

The invention also resides in certain details of construction which willbe hereinafter more fully described and finally embodied in the claims.

The accompanying drawing illustrates one form of the invention. Figure 1is a front view of a razor and magazine slightly separated but inposition for assembly, these parts embodying my invention. Figure 2 is atop view of the razor and magazine assembled and showing one blade beingfed into the razor which blade is ejecting another blade from the razor.Figure 3 is an end view of the shaving head of the razor shown inFigure 1. Figure 4 is a similar view with the positioning means of themagazine shown in section to illustrate the spreading of the bladeclamping members. Figure 5 is a perspective view of the magazine. Figure6 is a perspective view of a clip that may be used for loading a stackof blades as a unit into the magazine. Figure '7 is a central verticallongitudinal section of the magazine and its clip of blades. Figure 8 isa bottom view of one end of the magazine with the plunger partlywithdrawn. Figs. 9 and 10 show two sectional views of part of the razor,one with part of the magazine ready for insertion and the other withthis part inserted.

While various forms of razors and magazines can be used in carrying outmy invention the drawing shows the present preferred form. The razor isshown as provided with a handle 10 which has a pivoted front member 11movable laterally on the pivot 12 to throw its upper end 13 into or outof supporting position under a blade platform 14. The blade platformsupports the blade 15 and is provided with a suitable guard 16. At thecorners of the guard are the front stops 1'? against which the frontcorners of the blade 15 rest when in shaving position. The bladeplatform thus forms one clamping member of the shaving head and isprovided with an extension 18 which is pivoted at 19 so that it can belowered for cleaning purposes by swinging the handle member 11 andallowing the blade platform to drop. The other clamping member comprisesa top plate 20 on the end of an extension 21 which extends up from thehandle 10 and is usually integral therewith. The extensions 18 and 21are spaced apart and at least one of them has a spring action to allow alimited separation of them and also to allow them to clasp a blade whenreleased without operating the handle. The top plate has an abutment 22which is adapted to engage the back edge of the blade 15 and thusco-operate with the front stops 1'7 which engage the front corners ofthe blade to clasp the blade firmly in shaving position.

This construction of razor is well adapted for manufacture from sheetmetal and the resiliency of the shaving head is such as to enable aseparation of the walls 18 and 21 to release the blade from its frontengagement with the stops 1'7. At the same time the parts are stiffenough to hold the blade firmly in place and to prevent chattering ofthe blade in the shaving operation. It will also be noted that twomembers of the shaving head are rectangular, one fitting within theother and hinged together at the bottom. When separated by spreading thetwo extension walls 18 and 21, not only are the stops 17 and theabutment 22 pushed farther apart but the blade platform 14 and the topplate 20 are also separated slightly to ease up the contact on the flatfaces of the blade.

The magazine is adapted to hold a supply of blades and is equipped withmeans for forcing the blades out of the magazine. The feeding of theblades is, of course, in succession whereby the blades can be projected,one at a time, from the magazine.

A magazine is shown at 23. While the blades may be stacked in themagazine by hand they are usually arranged in a clip 24 and form a stack25. The clip is arranged in the magazine easily and is readily removablefor replacement. The

form shown comprises a magazine having an open bottom covered by a floorplate 26 which is hinged to the body portion of the magazine at 27 andextends up part way on the side at 28 and has a suitable finger piecefor its operation, as at 29. The floor plate is provided with a spring30 which presses the stack of blades upwardly, as the clips are providedwith openings 31 in the bottom which enables the spring to bear on thebottom of the stack 25. The clip 24 is readilyinsertable into themagazine from the back when the floor plate is lowered. The spring isout of the way as it is fast to the floor plate. The clip slides in on.

- 3'7 can clear the rear end of the stack 25. This allows the spring 30to push the stack up against the top of the magazine and the plungerthen picks up the top blade and can be used for pushing it out of themagazine. The magazine has a slot forming a blade outlet 38 in line withthe plunger and wider than the blades in order that each blade, whenejected, will have its cutting edge 39 clear the end 40 of the bladeoutlet. This insures the cutting edge of the blade against contact withthe slot and thus insures that it retains its keen edge.

The magazine and the razor have co-acting means for positioning thesetwo articles for feeding a blade from the magazine into the shaving headof the razor. The means shown comprises a projection or finger 41extending from one side of the magazine and it co-operates with therazor by fitting between the two extensions 18 and 21 of the shavinghead. This is clearly shown in Figures 4 and 9. The finger 41 is shownfiat to give it a wide bearing surface in the razor.

The positioning means has an additional function in spreading theshaving head to enlarge the blade channel in it. This function issecured by an element in the form of a raised part or hump 42 which actsto spread the bladeclamping members of the shaving head to separate thestops 17 and abutment 22. This releases the blade from the clampingaction. The released position is shown in Figure 4 and the clampingposition is shown in Figure 3. This freedom makes it easy to push theblade endwise from the razor when a following blade is pushed endwisefrom the magazine into the shaving head.

Another feature is the disposition of the parts to so locate themagazine that the front edge 40 of the outlet slot 35 is in rear of thefront stops 17 of the blade platform. The blade that enters the razor isthus pushed in a line that keeps its cutting edge 39 away from the endof the slot 38 and clear of the front stops 17.

When the plunger 35 has been pushed all the way in, the new blade isseated on the blade platform with its rear edge against the abutment 22.The magazine is then withdrawn. This enables the two clamping members ofthe shaving head to spring toward each other and the blade is pushedforward by the abutment 22 until its front corners engage the frontstops 17. In Figure 2 I have exaggerated the showing to illustrate theincoming blade and the outgoing blade .only a little to enable Anotherfeature of the razor is the assurance that the blade fed into the razorendwise from the magazine will not slide freely past the stop furthestfrom the magazine. The finger 41 is long enough to give sufficientbearing in the razor, usually being about half as long as the razor iswide. The hump 42 is therefore only in the half of the razor nearest themagazine and as the parts 14 and .21 are somewhat resilient the stop 17nearest the magazine is pushed well out but the one farthest from themagazine is relieved the used blade to be forced past it. The effect ofthis is to arrest a blade that has been too swiftly passed or projectedfrom the magazine when the forward end reaches the far corner of theshaving head.

The various elements of this invention are combined to provide acheapand simple mechanism for loading blades successively into therazor. This is accomplished without handling any blade individually,thus eliminating danger of cutting the fingers. The blades are fed intothe razor without any injury to the cutting edge of the blade as themechanism is designed to feed the blade with its cutting edge clear ofany guiding means until it is in shaving position and then only thecorners are in engagement with the stops.

Various changes can be made in the various parts without departing fromthe scope of my invention.
